Abstract ： The Glauber theory is used to investigate the reaction cross section of proton-rich nucleus 23 Al. A core plus a proton structure is assumed for 23 Al. HO-type density distribution is used for the core while the density distribution for the valence proton is calculated by solving the eigenvalue problem of Woods--Saxon potential. The transparency function in an analytical expression is obtained by adopting multi-Gaussian expansion for the density distribution. Coulomb correction and finite-range interaction are introduced. This modified Glauber model is suitable for halo nuclei. A dominate s-wave is suggested for the last proton in 23 Al from our analysis which is possible in the calculation of relativistic mean-field theory.
